I am going to be doing some experiments mounting thin kozo to various objects.
I realize that mounting to wood will expose them to acidic lignans and stain over time. The wood or stone could be coated with a clear acrylic barrier however. How the fact that kozo is itself wood, (that as far as I know has Not been purified of lignins ) plays into its durability is an interesting question when mounted to other organic objects.
What I am really interested in, and have been for some time, is mounting to stone, shaping it around the object as I"m doing now with silk and linen. I printed some works with liquid emulsion 10 years ago on Marble and very much liked to result but I hate darkrooms these days.
Yes, I've seen the Facebook site of the guy who is mounting on granite. It's strange because I started mounting some of my silk and linen geological series prints to granite and sandstone a year ago, but this kozo is sharper and more photographic.
Does anyone know if various rocks like marble, granite, or sandstone release acidic compounds that will stain or make the kozo brittle and dry? ( or not ).
Don't see that on the Aardeburg site
Thing is, in this case, I don't care if it does turn yellow or brown or deteriorates over a couple of decades, I'd just like to know if it will.
I assume mounting this thin kozo with polyvinylacitate PVA book binding glue could protect it from absorbing acids.
Anyway, kozo has been used in Chinese brush painting for thousands of years and many of those scroll paintings in museums still look quite good if not excellent.
